Maximal contact load at AC 1 with 230V:
2 contacts each with 6A
Gold contacts with 4-6μm layer thickness
When high voltages and currents are
switched, the layer of gold is destroyed
already after a few switching operations.
Once the gold layer is damaged due to the
switching of high loads, such a contact must
not be used any more for signal and control
current circuits.
Safe contact making is then only possible at
high loads with the formation of sparks.
